Yes, I tried a reinstall. The thing that is puzzling is that the file shows up simply because I launched Opera. All it's doing is checking for the preferred language. If it wasn't growing and is a "sore" on my desktop, I'd not worry.

If you're talking about the shortcut I used to launch, it's simply the exe for Opera. There are no %this or launch that. It opens to a blank page.

Update! I think I really fixed the problem, this time. I just didn't like having Opera pinned to my task bar. I did some more investigating - trying things. I went to "C:\Program Files (x86)\Opera\launcher.exe" and right-clicked and went to properties. I clicked the "Compatibility" tab. I checked "Run this program as an administrator". Now, my desktop right-click menu brings up Opera WITHOUT the debug.log. Here's hoping.

One more update. I removed run as admin and the debug.log file is back. I think I'll let sleeping dogs lie. It's just annoying. I really appreciate the advice about running as admin. I'm sure glad I decided to share my "success", otherwise I may have really had problems down the line. Thanks again, sgunhouse.

The third times the charm - update. My biggest complaint was the debug.log file glares at me from my desktop. Since I like my right-click menu and don't won't to pin Opera to the task bar, I figured what the heck. The file grows and has to be deleted at some point, but, even though it's on my desktop, my desktop is not on my SSD - dedicated OS - I'm not concerned with the write-delete function happening. I hid the file on my desktop. Out of sight, out of mind - but not quite. I use Crap Cleaner. I added an include to have this file deleted every time I run CC. I do this once a week and use Macrium Reflect as my back-up software. Now, out of sight and deleted weekly without having to remember it, and I'm good to go. I think I've recorded ALL the things that I've seen and done to remove this niggling file. I'm pretty sure I'm the only one in the Universe to experience this file being deposited on my desktop. I really appreciate all the comments and help I've received. I like to think this is what community is all about. I'm notified via email if you comment. I'm available to give you more information if you ask for it.
